This has nothing to do with the analyze feature. This is in the temp file finder tool... In this tool you can 'Backup and delete'... Before you could just 'undelete' one file at a time - now you can undo the entire 'delete-batch' at once (say you select 100 files, choses 'Backup and delete' and regret... Before you had to go into Backups -> Choose the backup -> Rightclick on every file and select 'Undelete'. Now you can say 'undelete all' and thus only has to do it once instead of 100 (with 100 files)).
